OmniPlex Data Acquisition System

The OmniPlex data acquisition system is a compact, flexible platform for high performance
neural data acquisition and powerful online spike sorting. The OmniPlex amplifier features
superior common mode rejection and programmable analog referencing for improved artifact
rejection before A/D conversion, and 16-bit, 40 kHz sampling to ensure your spike and
field potential signals are acquired with sufficient precision. At the heart of the
OmniPlex system is powerful software with a variety of manual and automatic spike
sorting methods, multi-user control, and mixed acquisition modes (single, stereotrode, tetrode).

Neuroexplorer is a neurophysiological data analysis package with a rich set of
analysis options and functions. NeuroExplorer can be used to analyze data files offline,
or used in realtime with the MAP System and OmniPlex System control software.

Spike Train Analyses

Continuously recorded signal analysis

Analysis of populations of neurons

Free trial version available

Offline Sorter

Offline Sorter (OFS) version 3 is a powerful, easy-to-use tool for viewing and
classifying action potential waveforms (spikes) collected from single electrodes,
stereotrodes, and tetrodes. Spikes can be displayed as points in either 2D or 3D
feature space, where a variety of manual, semi-automated, or fully automated
clustering techniques can be applied in order to classify (sort) the spikes.
OFS can also perform spike extraction on continuously-recorded neural data
using a variety of different thresholding methods. OFS allows verification of
sorting through a variety of displays, and can calculate cluster separation
statistics and sort quality metrics. The sorted spikes can be exported in
several formats for subsequent analysis.

Commutators, electrodes & microdrives

Plexon offer a wide variety of accessories to complement their neuro-acquistion systems.

Commutators, allowing the test animal to move freely within the environment.
